True that. I stopped gaming. I play 'Internet Reversi' every now and then. I use the computer mostly for school stuff and browsing online. Wireless mice are the worst choice for FPS. It's OK for RTS or TBS.

Deatadder is by all means not a "more RTS" mouse. Lots and lots of CS players use it. I’m talking about top teams who get paid to play the game.

You are a 100% correct here! "no hardcore gamer uses a wireless mouse"

Like I sad in the beginning DPI is overrated. If you set your mouse to 4,000DPI you won’t be able to play because one small mouse movement will give you a 360 degrees turn lol. I have "1800dpi Razer Precision™ 3G infrared sensor" in Deathadder and I use about 800 DPI and 1.3 sensitivity in game (very very small) Ideally the way I know that my mouse sensitivity in game is good is when I can do a 180 degrees turn, no more no less for me 2 much sensitivity is hard to make "headshots" but you do need that speed to make quick turns if someone is shooting u from behind. I guess its all personal preference.

DPI is not totally overrated. If you are a low sensitivity player, the high DPI mice are great. Higher DPI mice are able to track more accurately when your swiping the mouse across the table compared to low DPI mice.
